MILTON D. KEISER, OF PRAIRIE CITY, IOWA.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 615,558, dated December 6, 1898. Application filed June 4, 1898. Serial No. 682,565. (No model.)

To all whom it Tnay concern:

Be it known that I, MILTON D. KEISER, of Prairie City, in the county of Jasper and State of Iowa, have invented a new and Improved Acetylene-Generator, of which the following is a full, clear, and'exact description.

This invention is an acetylene-generator in which the gasometer is formed of two tanks communicatingwith each other and arranged in a peculiar manner, owing to which arrangement the water contained in the tanks is made to effectively flood the carbid-chamber according to the volume of gas in the gasometer.

This specification is the disclosure of two forms of my invention, while the claims define the actual scope of the invention.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a side elevation of the invention, and Fig. 2 is a fragmentary plan view showing the carbid or gas generating. chamber and a part of the gasometer.

My invention has a gasometer-tank 7 and the fluid-pressure tank 6,the latter of which is higher than the former and is provided with a closure 8, which permits access to be had to the interior of the tank 6. The tank 6 has a pipe 9 leading from the top thereof to a chamber 10, from which chamber passes a blow-=off and air-vent pipe 11. From the chamber 10 a pipe 12 passes downward to and communicates with the lower portion of the tank 7, whereby the tank 7 is also connected with the chamber 10 and pipe 11.

The tanks 6 and 7 are connected with each other at their lower portions by means of a pipe 14:. Extending centrally through the tank 7 and connected with each head thereof is a vertical brace-rod 15, strengthening the tank against internal pressure. A gage 16 is provided for the tank 7, by which to show the height of the Water in the tank.

Supported on the tank 7, by means of upwardly and outwardly extending braces 17, is the carbid or gas-generating cylinder 18, the bottom head 19 of which has a central depression 20, from which passes a pipe 21, communicating with a pipe 22 from the bottom of the tank 7. A cook 23 commands the passage of Water from the tank 7 to the pipe 21, and a cook 24 is connected withthe end of the pipe 22, so that by closing the cook 23 and opening the cock 2st the chamber 18 may be drained of its liquid contents. The removable upper head 25 of the chamber 18 is held in place by clamps 31. V

Contained in the chamber 18 are two or more carbid -buckets 33 with foraminated sides. These buckets are each provided with a bail or handle 34 and are imposed one upon the other, the purpose of such arrangement being to prevent the simultaneous contact of the water with all of the carbid, as well as to avoid the contact of the ashes or burned carbid with the carbid which has not been sub jected to the action of the water. Leading out from the top of the chamber 18 is a pipe 35, commanded by a valve 36. This pipe runs into the upper port-ion of the tank 7 and connects with a pipe 37, which passes down to the bottom of the tank 7 and communicates with a coil 38, contained in the bottom of the tank 7. Finally the coil 38 communicates with a vertically-extending pipe 39, held rigidly by a bracket 40 and running up to the top of the tank 7, where the pipe 39 discharges into the tank. The gas generated in-the chamber 18 passes through the pipes 35 and 37 down to the coil 38 and is cooled in said coil, after which the gas passes upward through the pipe 39 into the tank 7. From the tank 7 the gas is drawn by a service-pipe 41. The tanks 18 and 7 being in communication by the pipes 39, 38, 37, and 35 have equal pressure of gas therein. The volume'of gas in the tank 7 regulates the height of water in said tank. As the volume of gas in the tank 7 decreases the height of the water in said tank is increased, thus causing the water to rise in the chamber 18, and upon contacting with the carbid therein more gas is generated, which upon. entering the tank 7 depresses the level of waterin said tank and withdraws the water from the chamber 18, thus stopping the generation of gas. By

these means the apparatus acts automatically to regulate the generation of the gas according to the demands of the consumption of the gas.

The tank 6 coacts with the tank 7 to receive water from and discharge water to the tank 7, according to the pressure of gas Within the tank 7. Should the pressure of Patent- 5 1. An acetylene-generator having a gasometer-tank and a fluid-pressure tank communicating with each other, a pipe leading from the lower portion of one tank, a'pipe leading from the upper portion of the other tank, a blow-off chamber with which each of said pipes communicates, a third pipe passing from the blow-off chamber, a carbid-chamber,

and connections between the carbid-chamber and said first tank.

2. The combination of a gasorneter-tank and a fluid-pressure tank, the tanks being in communication with each other at their lower portions, a pipe leading from the lower portion of one tank, a pipe leading from the upper portion of the other tank, a blow-0E chamber with which said pipes communicate, and a third pipe passing from the blow-off chamber.

3. The combination of a gasometer-tank and a fluid pressure tank communicating with each other at their lower portions, a pipe leading from the lower portion of one tank, a pipe leading from the upper portion of the other tank, and a third pipe having communication with the two first-named pipes and corn municating with the atmosphere.
